Sci-Fi Love one of Anorak City's favourite blogs is hosting the third in a series of Torchwood live blogs tonight - join the fun below.

Well, didn't see that one coming ...

The third episode of Torchwood : Children Of Earth was slower paced than the first two, instead building the tension and general feel of unease.

The confrontation between scheming Frobisher and the 456 was brilliantly played.

Just hope that the aliens (if indeed they are aliens, rather than the kids who were kidnapped back in 1965) don't look rubbish once they emerge from their tank.

And, just a thought, wouldn't that be similar to the way the last remnants of the human race came back as killer orbs to serve the Master?

But the masterstroke was the final scene, in which we learned Captain Jack's dark secret.

(Not saying exactly what in case any of you are still playing catch up out there).

Turned the whole thing on its head, and set up tonight's fourth outing well.

Here's the trailer for Episode 4.

This South African sci-fi is already being heralded as our last, best hope of a classic film this summer.

And the second glimpse certainly leaves you wanting more...

Torchwood's mini third season is proving to be quite a ride and a little bird tells me tonight's episode is an absolute cracker.

And we're told to expect a huge cliffhanger on Day Three as the shift in tone gets even darker.

Captain Jack overdid the new diet ...

Torchwood in ruins, Ianto & Gwen on the run, Jack in bits (literally), Gwen & Rhys flee in potato truck, I'm pregnant, Whitehall PA spills beans, Jack grows new body, Jack encased in concrete, creepy kids chanting, Ianto drives forklift, drops Jack over quarry. Jack back in the buff, we are coming tomorrow, boffins build gas tank, creepy janitor hisses.

Roll on Wednesday. See next page for the trailer...

Someone tell Torchwood!

To mark the 25th anniversary of Ghostbusters and the launch of the new Ghostbusters Video Game the folks at French Connection have come up with these t-shirts.

The T-shirts retail at £25...

Turkish style! Sorry I know I said I would stop. It is nearly out of my system...

SO now we know why David Tennant had to hang up his coat.

He'll be playing the villain in the new St Trinian's movie.

Tennant, 38, will appear as the evil Pomfrey in St Trinian's: The Legend of Fritton's Gold, which hits UK cinemas on or around December 18.

He'll be alongside Girls Aloud's Sarah Harding, Colin Firth and Rupert Everett - who all appeared in 2007's St Trinian's.

Ashes to Ashes actress Montserrat Lombard will also appear.

In the new movie, the girls of St. Trinian's are on the hunt for buried treasure after discovering headmistress Miss Fritton is related to a famous pirate.

The original 1950s St Trinian's films - including The Belles of St Trinian's and Blue Murder at St Trinian's - featured stars including Joan Sims and Barbara Windsor as naughty schoolgirls.

The 2007 reworking, which also starred Gemma Arterton and Russell Brand, breathed new life into the franchise, and took £15m at the UK box office.

Stateside mag TV Guide has been quizzing the stars of Lost about how they think it might all end.

Elizabeth Mitchell (Juliet)

"Like the end of Stephen King's The Dark Tower, I think something will happen where we all go back to where we were.

"Juliet was never brought to the island. The plane never crashes. These people have never met.

"But because of the odd nature of time, we keep on getting drawn back into the same situation again.

"So basically, the ending is just another beginning."
